java.util.zip.ZipException: duplicate entry: android/support/v7/graphics/drawable/DrawableUtils.class

Question

I just updated my support library from 23.0.0 to 23.1.0 and now when I build the project, I get this error :

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
> com.android.build.transform.api.TransformException: java.util.zip.ZipException: duplicate entry: android/support/v7/graphics/drawable/DrawableUtils.class

Here is my app level build.gradle:

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}


apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
apply plugin: 'com.google.gms.google-services'

android {
    compileSdkVersion 23
    buildToolsVersion "23"
    defaultConfig {
        applicationId 'com.galleri5.android'
        multiDexEnabled true
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 6
        versionName "0.6"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}


repositories {
    mavenCentral()
    mavenLocal()
    jcenter()
    maven { url 'https://maven.fabric.io/public' }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:23.1.0'
    compile 'com.android.support:support-v4:23.1.0'
    compile 'com.squareup.picasso:picasso:2.5.2'

    compile('com.crashlytics.sdk.android:crashlytics:2.5.2@aar') {
        transitive = true;
    }
}

What am I getting this error? I want to use the latest version of support library. How can I fix this issue? I read this SO thread and the solution didn't work. It gave more errors in my codebase. Also, I am not using JARs. Any help would be highly appreciated. Thanks.

I ran into the same problem in my React Native Android project, and this is what made it work for me:

cd android

./gradlew clean
